Passenger rail service by Amtrak's Pennsylvanian passes through once daily in each direction on the Pittsburgh Line, but does not call in Monroeville.

Many freight trains arrive via the same track to Norfolk Southern's Pitcairn Intermodal Terminal which straddles the Monreoville-North Versailles border in the Turtle Creek valley.

The Westmoreland Heritage Trail is a rail-trail that connects cyclists and pedestrians in Monroeville to neighboring Trafford and Murrysville along the right of way where the Turtle Creek Industrial Railroad once ran.
